IMPROVEMENT IN STEERING APPARATUS.

Specification forming part of Letters Patent No. 216,874, dated June 24,1879; application filed March 8, 1879.

To all whom it may concern:

Be it known that I, SAMUEL Gr. MARTIN, of South Amboy, in the county ofMiddlesex and State of New Jersey, have invented a new and ImprovedSteering Apparatus, of which the following is a specification.

My present invention is an improvement upon the steering apparatus shownin Letters Patent granted to me November 12, 1878; and the inventionconsists in certain novel features of construction and combination,whereby the apparatus is rendered more compact and adapted for smallervessels.

The construction is shown in the accompanying drawings, wherein Figure 1is a plan view and partial section of the apparatus as applied to thedeck of a vessel. Fig. 2 is a side elevation. Fig. 3 is a sectional viewof the four-way valve.

Similar letters of reference indicate corresponding parts.

I make use of a single cylinder, A, fitted with two piston-heads, a a,to which heads the Wire ropes or chains 1) b from the tiller areseparately connected.

The cylinder A is placed crosswise of the deck, and the ropes I) pass ateach side of the vessel over friction-rollers, as shown. Onepiston-head, a, is shown, connected with a rod, a, that passes throughthe headof the cylinder for connection of rope b. The other piston-headhas no rod; but the rope b extends within the cylinder and is attachedto the head a. The last-named construction permits placing of thefriction roller d nearer to the cylinder than when a ri id piston-rod isusedbut the apparatus may be fitted in either manner. I

The cylinder A is supplied with steam at either end from boiler 6,through pipes f and 9, according to the direction which the heads a areto be moved, by manipulation of fourway cook B, that operates a four-waycock in pipe f.

When steam is admitted to one end of the cylinder A, one head, a, ispressed forward,

while the other head is moved by its rope I) in the same direction bythe movement of the tiller.

Each head a is fitted with a valve, 0, that permits escape of steam fromthe space between the piston -heads. The cylinder exhausts plished byexhausting steam behind either of v the pistons.

In some cases, where a short cylinder is preferred, the motion of theropes b will be multiplied by the use of a block, h, that moves withrope b and draws upon the rope I), which passes from the tiller to afixed point, in the usual manner, for multiplying motion by pulleys. n

The same arrangement will of necessity be used in connection with eachrope I), but, when cylinders of sufficient length can be used, may bedispensed with.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent- 1. The combination, with cylinder A, having pistonsa, whose rods connect with the tillerropes, of the pipe f, leading fromthe boiler, the pipe g, connecting it with the ends of the cylinder, andthe four-way cock B at the junction of said pipes, as and for thepurpose specified.

2. The combination, with the tiller-ropes b, that are connected with thepistons of cylinder A, of the pulley h, arranged for multiply ing themotion, as and for the purposes set forth.
